Autodesk Revit MEP

[#1]

I am playing around with layer mapping in Revit. I can easily modify the layers to export to Autocad. In autocad, we use exist and new layers. (M-Equip-exist, M-Equip-new). Is there a way to associate the layer mapping to the phase in revit? Thank you in advance for any assistance.

There is a small array of additional prefixes/suffixes that can be incorporated as needed. Go to Application Menu ▼ Export » CAD Formats » DWG. Click "Modify Export Setup" (the "" towards the top). Under the Layers tab, scroll down and select the Category(ies) to which you wish to append a prefix/suffix. Click "Add/Edit.." under the 'Layer modifiers' column. In the following dialog, you may choose from the available modifiers and add/arrange them as desired, along with adding separators.

Normally, I would suggest adding "{Phase Status}" (see my comments below), but in your particular case, you may need to add "{Phase Created}" instead (with a dash listed as a separator beside the primary Category name).

Demolition plans should be exported using the modifier "{Phase Status}". A separate Export Setup configuration can be created that is dedicated to demo. See my comments below.

Additional comments:

{Phase Created} will add exactly this to the Layer name in AutoCAD. This makes exporting Demolished elements tricky, since those will be grouped along with the other existing elements.

{Phase Status} will add a designator to the Layer name in AutoCAD based on the Phase settings of the elements. This will return such a suffix as "-EXST" or "-DEMO", with NO designation added for NEW elements, hence the alternate suggestion above. Note that this modifier comes with a built-in separator.

If you would like any more info or help, don't hesitate to ask!

Corey,

Thank you for your quick response! I have tried both of your suggestions, and both work exactly as you describe. I am currently working on "tweaking" some export options so we can get the exact result we are looking for. Thanks again!

You can customize the Layer Modifiers in the 'Modify DWG/DXF Export Setup' dialog, under the 'Layers' tab. Scroll down towards the bottom of the list to Modifiers. Here, you can define exactly what you wish to be added to the AutoCAD Layer name.
